Hey guys,
I'm using dpdk 16.4 and fm10k card. According to the code, there's no support for disabling vlan stripping and VLAN QinQ in pmd fm10k.
Does anybody know why? If there's any way to work-around it, or when is a behavior change expected?
I need my VF to receive the packets with the VLAN headers.
Even if it's possible to change this configurations through the linux kernel fm10k driver?
Thanks!

Yes, HW will always strip it and driver will copy it into
(struct rte_mbuf *)mbuf->vlan_tci.

VF can read from rte_mbuf.
